PowerPak incompatabilities?
I'm thinking of getting an NES PowerPak and am curious as to what games most notably do not work on it. I am assuming Mr. Gimmick, japanese version, might not because of the extra sound chip or at least the music won't sound as good, perhaps?
I'd assume most unlicensed games with their funky mappers would most likely be on that list too. Can anyone give me some ideas?

I was browsing it a bit and it seems any games that use the MMC5 mapper(Castlevania 3 etc) won't work.
I believe the Japanese version of Castlevania 3 works fine, since it used the MMC6 mapper, which is supported by the powerpak.
